What is the most common type of nebula? One of the most common types of emission nebula occurs when an interstellar gas cloud dominated by neutral hydrogen atoms is ionised by nearby O and B type stars. What is it like inside a nebula? Nebulas are mostly very thin material and would count as a […]
What is a limitation of comparative investigations?
What is a limitation of comparative investigations? Limitation of comparative investigation is that when it is done on a huge population, huge amount cost is required. Explanation: Benefit of comparative investigation is that we can get descrete information about specific breed or species. It is important for the study of behaviour of many organisms. What […]
Which has more kinetic energy hot or cold?
Which has more kinetic energy hot or cold? Kinetic energy is related to temperature. The molecules in a glass of warm water have more kinetic energy (they move faster – see Racing Molecules) than the molecules in a glass of cold water. The temperature of a substance is the average* amount of kinetic energy its […]
How much energy does glycolysis release?
How much energy does glycolysis release? Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy. Which respiration releases the most energy? Summary. Aerobic respiration is […]
Why does cream swirl in coffee?
Why does cream swirl in coffee? In the video below, MIT scientists explain that when the drop of cream first hits the surface of the coffee, a bit of air becomes trapped between the drop and the rest of the liquid. Anyone who has admired the swirling patterns cream makes in coffee can appreciate this […]
What causes Peltier effect?
What causes Peltier effect? The diffusion of carrier causes a diffusing potential at the junction, which hinders the further diffusion through a drift current. Conversely, when a current comes through these two junctions, a temperature difference in the two junctions has been created, which is called Peltier effect. What is the difference between Peltier effect […]
What are the two types of reproduction Class 7?
What are the two types of reproduction Class 7? Reproduction is carried out through two modes: Asexual reproduction. Sexual reproduction. What are the two types of asexual methods? Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals. What is reproduction 7th? Reproduction […]
What is the formula for communication channels?
What is the formula for communication channels? The communications channels formula is N * (N-1) / 2. It is a way to numerically show the importance of proper communications management on a project. We all have a “gut feeling” in regards to this and most people would agree that “the larger the project, the more […]
What form of energy is used to light a match?
What form of energy is used to light a match? chemical energy What energy does a hair dryer convert? Hair dryers use heating element and motor-driven fan to convert electric energy into convective heat. Which two forms of energy does a hairdryer converts electrical energy into? Electrical energy entering the hair dryer is converted to […]
How many atoms are in 1 kg of uranium?
How many atoms are in 1 kg of uranium? so the answer is 2.56*10^24 atoms. How much uranium can power a city? Uranium as a fuel for nuclear power Over 50 more reactors are under construction and about another 100 are planned2. A typical 1000 megawatt (MWe) reactor can provide enough electricity for a modern […]
